Echoing earlier suggestions of Fire Emblem: Three Houses, Overcooked/2, and Super Smash Brothers Ultimate. Love all of them, but may want to skip Smash Ultimate if you're looking for more than just pure action. It's also a game I'd only recommend if you have friends that play it too.
A few of these are remasters of games released for other consoles, but are some of my favorites:
Story of Seasons: Friends of Mineral Town
Rune Factory 4: Special
Pokemon: Let's Go Eevee/Pikachu
Atelier Ryza: Ever Darkness and The Secret Hideout
Sakuna of Rice and Ruin is a recent release that combines the craft of making rice and fun side-scrolling action. I haven't played it yet, but it's one I'm looking at buying. Take a peek to see if it may be something you enjoy.
Another game to look out for this year is Hyrule Warriors: Age of Calamity, which releases on November 20.
